Santa Susana is notorious for a dangerously cavalier attitude about chemical safety. For years they burned toxic chemical waste in open pits. They filled barrels and shot them with rifles until they exploded. One person was killed in 1994. They disposed of sodium coated parts by letting them burn in the same open-air pits.
